LOL, BOOM 80 damage in your face! At first I was thinking "Wow, 2 Kel-Dors is a lot of points in a 150 point squad" but now I see your purpose.
In a really competitive environment, I would probably be tempted to drop one of the Kel-Dors for activations, and then use Lobot to bring in another one if you decide you want it. Then you could also do MTB and MORE activations if you'd rather that, and you would have either Kyle's Grenades for trying to kill the MTB, or the other Kel-Dor. Although, if you run the 2 Kel-Dors with the MTB, then you wouldn't even have to use Kyle's Grenades in order to do the 80 damage boom on somebody.
Not a bad idea overall though. Other than the Kel-Dors, Kyle will have a rough time against shooter heavy squads.
